Title: Improvements in or relating to the production of nuclear fuel
Inventor: HUDDLE ROY ALFRED ULFKETEL
IPC: G21C3/62
Filed: 1964-07-29
Abstract: Particles of nuclear fuel metal carbides having a carbon content in excess of the stoichiometric ratio are prepared by mixing a corresponding oxide with carbonaceous grains and a polymerizable binder, forming into spherical particles, separating a selected size fraction, heating in an inert gas to reduce the oxide to carbide, and then coating with pyrolytic carbon.  A fluidized bed process may be used for the reduction and coating, using argon as the fluidizing gas and adding methane for the coating step.  In examples, powdered enriched UO2 is mixed with powdered carbon and furfuryl alcohol, the mixture is granulated, the granules rounded to shape in a planetary mill, sieved, treated with HCl gas to polymerise the binder, and then reduced at 1800 DEG C. in argon.  The particles formed may have a carbon to nuclear fuel metal atomic ratio of between 5:1 and 15:1 and a particle size of 300-500 microns.  Reference has been directed by the Comptroller to Specifications 878,927 and 945,063.

Patent GB-1512731-A (GB)
Title: Process for removing and recovering precipitation agents from precipitate containing proteinous substances
IPC: C02F1/52
Filed: 1975-07-21
Abstract: An alkaline earth metal compound is added to the sludge in a sufficient quantity to bind the proteins. Generally, the pH is then already greater than 6.5, otherwise it is adjusted to above 6.5 by addition of an alkali metal hydroxide or an alkaline earth metal hydroxide. The sludge is then heated to a temperature which is above the coagulation point of the proteins present, a water phase being released which is separated off. This water phase contains the precipitant and can be reused for precipitating proteins. The advantage of the process described here is that not only is a concentration or thickening of the precipitated protein-containing sludge achieved, but also the precipitant is recovered for further use.

An image, such as that produced on the screen 1, Fig. 1, of the brightness amplifier tube BA of an X-ray, microscope or other system, is reproduced at will on the input elements 5, 7, 10 of a cine, television, or still, camera by reflecting the image at a prism 2 into a collimating unit 3 so that the parallel beam produced therefrom may be reflected by the 45 degrees mirror in position 4 into the cine objective 6 or when in position 4' into the still camera objective 11 or, with the mirror raised, pass directly to the television camera objective 8, the mirror being moved between positions 4, 4', only when raised from its operative position. The mirror may be semitransparent so that when in position 4 or 4' the image is reproduced simultaneously at 7 and either 5 or 10. The mirror may be moved longitudinally by a motor (16), Fig. 3 (not shown), rotating through gearing (17), (18), a nut (14) threadedly engaging a screw (13) carrying the mirror. A vane (20), Fig. 4 (not shown), held against an electromagnet (E2), slides within a slot (19) in screw (13) to prevent rotation of the mirror. When an end member (21) on screw (13) actuates a micro-switch (C3), the electromagnet is de-energized, the friction between nut (14) and screw (13) causes the latter to be rotated until the vane (20) contacts a second electromagnet (E1) which has been energized, and the mirror has now been rotated from position (4) to (4'). When limit switch (C1) is actuated the screw (13) stops with the mirror fully retracted from its active position. By reverse actuation of motor (16), the mirror can be moved back to its active position, limit switch (C2) being actuated when this is reached.
